RAILWAY-TRACK CONSTRUCTION.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed June 11; 1902. Serial No. 111.146.

To all whom it may concern:

Be it known that I, HENRY B. A. Knisnn, of Akron. in the county of Summit and State of Ohio, have invented a new and useful Railway-Track Construction, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side elevation showing a portion of a railroad track constructed in accordance with my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a cross-section. Fig. 4 is a top plan view, showing the construction of a curved portion of the track. Fig. 5 is a crosssection of Fig. 4. Figs. 6 and 7 are side elevations showing modified forms of construction, and Fig. 8 is a cross-section of a double track, showing a wa ter shed and drainage system.

My invention relates to the rail carrying structure of railroads, and is designed to provide an improved supporting bed which will do away with the necessity for ties and afford a continuous support throughout the entire length of the track.

In the drawings, referring to the form of Figs. 1., 2 and 3, 2, 2, represent the rails and 3 the supporting bed therefor. This bed is formed of long plates of a width roughly approximating the length of the present ties, and of a length equal to the space covered by a series of such tiespreferably 80 to 100 feet .long. These plates, which are a common article of manufacture, are transversely corrugated, in this form, preferably by passing the flat plates between corrugated bending rolls. The ends of the plates at their juncture may be secured to each other by a line of rivets 4, as shown, or in any other suitable way. The rails which may rest upon the apices of the corrugations may be secured to the plates by rivets 5, as shown, or by any other fastening devices. 7 i

In curved portions of the track, I preferably employ the form shown in Figs. 4 and 5. In these figures the plate is curved by making the corrugations deeper or closer at one side of the plate than at the other, the corrugations being successively deeper or closer transversely, as clearly shown in Fig. 5. The plate is thus given a uniform curve of any desired degree of curvature, while the corrugations are retained, as in the straight portions of the track.

Instead of using the transversely corrugated plates I may use fiat plates which are suitably strengthened to carry the load. Thus in Fig. 6 I show a bed consisting of a flat plate 6 with a series of angles 7 extending transversely along its lower face with their flanges riveted or bolted thereto; and in Fig. 7 I show a similar construction where the strengthening members consist of small I-beams 8 similarly secured to the lower face of the bed.

In building the track structure, 1 preferably apply water to the filling material to cause it to settle into place along the desired level; and I may also ram the dirt foundation to settle the road bed into place before applying my metallic bed thereto. section is to be raised in case of settling or for other reasons, I preferably pour a pasty self hardening composition between the track plates and the earthy bed. In Fig. 8, I show a double track system, constructed in accordance with my invention, the rails being supported upon transversely corrugated plates.

In order to protect the road bed from the elements I show in this form a trough or gutter 9 between the two tracks, and preferably secured to the inner ends of the corrugated plates. Drain pipes 10 lead from this gutter to prevent water soaking through the road bed.

To protect the outer parts of the bed, I provide inclined plates 11, forming water sheds, which are preferably fastened to the outer parts of the corrugated plates and shed the water from the outer parts of the bed, these preferably being inclined downwardly and outwardly. The bed being thus kept in a dry condition will not be affected by frost. These water sheds and gutters may be formed of cement instead of metal plates, and preferably so formed where the original track is poured up of cement.

The advantages of my invention result from the doing away with the ordinary ties and ballast and replacing the ties by the continuous supporting plates of a single thickness throughout, except at the joining ends of the plates. I

The corrugations are much closer together than the ties now used, and hence the rails may be decreased in weight and height; a broken rail could not derail the train as at present, since the broken parts would be firmly held. The side thrusts of the wheels are firmly resisted by the longitudinally extending plates, and the track cannot creep. The bed beneath the plates is If the track thoroughly protected from the elements and the road bed kept in good condition.

The plates are easily formed and will provide a track support at a comparatively low cost per mile.

Many changes may be made in the form and arrangement of the plates, their connections, etc. without departing from my invention.

I claim:

1. A continuous track support consisting of transversely stiifened metallic plates secured directly to each other at their ends, means for securing the rail-bases directly to said plates, said stiffened plates formingthe sole support for the rails; substantially as described. A track support consisting 01' metallic plates secured together end to end, each plate extending the distance of several ties, said plates having transverse corrugations; substantially as described.

3. A track support consisting of metallic plates secured together end to end and having transverse corrugations each plate extending the distance of several ties, said plates having water sheds at their side edges; substantially as described.

4. A curved track support having transverse corrugations, said corrugations being arranged to support one rail at a higher level than that of the other; substantially as described.

5. A curved track support having transverse corrugations which are deeper or closer at one side than at the other; substantially as described.

6. A curved track support having transverse corrugations which are flattened along one side; substantially as described.

7. A continuous metallic track support running longitudinally beneath the rails and composed of transversely stiffened plates to which said rails are directly secured; substantially as described.

8v A continuous track support consisting of transversely stiffened plates fastened end to end in combination with a cement filling interposed between said plate and a compacted earth surface; substantially as described.

9. A continuous railroad track support consisting of metallic plates of suitable thickness, each plate extend. ing the distance of several ties, said plates being provided with transverse corrugations, and having means for the attachment thereto of the rails; substantially as described.

10. A continuous track support consisting of metallic plates of suitable thickness, rolled in the direction of their length, said plates being transversely stiffened and having longitudinally disposed means thereon for the attachment of the rails; substantially as described.

In testimony whereof, I have hereunto set my hand.
